Substitute Part Grouping Explanation

Substitute parts for the ABLS-7.68MHZ-D-4-H-T are determined by strict equivalence across the following critical parameters:

• Frequency: 7.68 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 100 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.449" L x 0.185" W, Height 0.165" max (exact match required)

The ABLS-7.680MHZ-D-4-Y-T meets all electrical and mechanical substitution criteria. The primary difference is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both the ABLS-7.68MHZ-D-4-H-T and ABLS-7.680MHZ-D-4-Y-T are active products from Abracon LLC with identical electrical specifications and mechanical dimensions. Both parts are ROHS3 compliant and REACH affected, meeting the same regulatory requirements.

Selection between these parts should be based on packaging requirements. The ABLS-7.680MHZ-D-4-Y-T in Tape & Reel format is suitable for high-volume automated assembly processes. The ABLS-7.68MHZ-D-4-H-T in standard packaging may be preferred for lower-volume applications or manual assembly workflows.

Both parts provide equivalent performance in circuit applications requiring a 7.68 MHz fundamental mode crystal with 18pF load capacitance and 100 Ohms ESR across the -40°C to 85°C operating range.

Frequently Asked Questions (FAQ)

Q: Can ABLS-7.680MHZ-D-4-Y-T be used as a direct replacement for ABLS-7.68MHZ-D-4-H-T?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. The substitute is supplied in Tape & Reel format while the main part uses standard packaging. Circuit performance and PCB footprint compatibility are identical.

Q: What is the significance of the packaging difference between these parts?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume manufacturing. Standard packaging is typically used for lower-volume applications, manual assembly, or component evaluation. The electrical and mechanical specifications remain unchanged.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both ABLS-7.68MHZ-D-4-H-T and ABLS-7.680MHZ-D-4-Y-T operate across -40°C to 85°C. Temperature performance is identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH affected. Regulatory compliance is equivalent.

Q: What determines whether a crystal can substitute for the ABLS-7.68MHZ-D-4-H-T?

A: A substitute crystal must match all of the following: 7.68 MHz frequency, ±30ppm tolerance, 18pF load capacitance, 100 Ohms ESR, fundamental operating mode, -40°C to 85°C temperature range, HC-49/US package, surface mount mounting type, and 0.449" x 0.185" x 0.165" max dimensions.
